A New Era in Psychiatric Genetics?

      Several major psychiatric disorders, including schizophrenia, bipolar disorder, and autism, have been shown to have strong underlying genetic components and are among the most heritable of genetically complex medical illnesses. However, 30 years of psychiatric genetics research demonstrates that high heritability does not mean ease of finding genetic causes. Indeed, the history of psychiatric genetics is largely a story of unreplicated discoveries and unrealized expectations. At the risk of raising expectations once again, this disappointing history may be about to change, and a new chapter of discovery may be about to begin.
